Welcome to the exciting world of uSCXML, where you can interact with state-charts through SCXML files seamlessly! This guide will walk you through the essentials of installing, using, and troubleshooting uSCXML, so you can jump right into your project.

What is uSCXML?

uSCXML is an advanced platform designed for working with state-charts defined as SCXML files. Think of it as a sophisticated orchestra conductor, efficiently managing and transitioning the various states of your software components. It includes:

• libuscxml: A C++ library featuring an interpreter and other functionalities.
• uscxml-browser: A command-line interpreter for SCXML documents.
• uscxml-transform: A toolkit for transforming SCXML into other languages like ANSI-C and VHDL.

Installation of uSCXML

The installation process involves building the source code. Here are the steps to follow:

1. Check for any open issues or instructions.
2. Build from the source as no released installers are currently available.
3. If needed, after building locally, create installers using the make packages command.

Documentation and additional resources are found on our GitHub pages.

Getting Started with Basic Commands

Here are two core functionalities to help you get started:

Using as a Library

Imagine you have a highly intelligent robot (the Interpreter) working on a task. Here’s how to set it up:

uscxml::Interpreter scxml = uscxml::Interpreter::fromURL(...);
scxml.on().enterState([](const std::string sessionId, 
                         const std::string stateName, 
                         const xercesc_3_1::DOMElement* state) {
    std::cout << "Entered " << stateName << std::endl;
});
while(scxml.step() != uscxml::USCXML_FINISHED) {
    ...
}

In the analogy of our robot, it is constantly checking its progress and communicating updates. If it encounters a finished state, it stops behaving for that particular task.

Command-Line Usage

If using the command line, you can interpret a state-chart by executing:

$ uscxml-browser https://raw.githubusercontent.com/tklab-tud/uscxml/master/test/w3c/nulltest436.scxml

This tells our robot to follow a specific set of instructions outlined in a SCXML document.

Troubleshooting Common Issues

If you encounter any hurdles while using uSCXML, here are some helpful troubleshooting tips:

• Ensure that all dependencies are correctly installed and linked. These include libraries such as libcurl and Xerces-C++.
• Check the open issues on GitHub for updates or similar problems faced by other users.
• For any unexpected behavior or bugs, consider cleaning your build environment and rebuilding the uSCXML from scratch.
